Etale double covers of cyclic p-gonal covers

Algebraic Geometry 2019-06-20 v2

Abstract

This paper computes the Galois group of the Galois cover of the composition of an \'etale double cover of a cyclic pp-gonal cover for any prime pp. Moreover a relation between some of its Prym varieties and the Jacobian of a subcover is given. In a sense this generalizes the trigonal construction.
